The MODIS Characterization Support Team (MCST) is dedicated to the production of a high quality MODIS calibration product. MCST developed the L1B algorithm and all parameters necessary to run the code, and develops the quality assurance and verification of L1B product enhancements. The MCST flight operations team supports MODIS operations on orbit through command and control of the instrument. Responsibilities include developing MODIS operations scenarios, creating the operations database, monitoring instrument health and safety, and operating the MODIS on-orbit.
The purpose of the MODIS Instrument Operations Team (IOT) is to plan, schedule, and monitor MODIS activities. The MODIS Instrument Operations Team schedules a daily set of Operational Activities using the Instrument Support Toolkit (IST) software package provided by the EOS Flight Operations Segment.
MCST is dedicated to the production of a high quality MODIS calibration product. This product is a precursor to every geophysical science product. MCST works for the Science Team Leader and is responsible for developing and maintaining the calibration product (L1B algorithm).
Terra MODIS band 30 detector 7 (production order) had a sudden jump on March 21, 2013 and NEdT started to exceed the specification (0.25) on May 4, 2013. Analysis shows that the NEdT exceeds the specification (0.25) for more than 20% of scans within a granule consistently for a period of two weeks, meeting the criteria for a MODIS TEB detector QA change from “Operational” to “Noisy”. MCST has implemented a QA status change for Terra MODIS band 30 detector 7 from “Operational” to “Noisy” in both the C5 & C6 LUT.
MCST arranged a workshop (via telecon) to discuss the status, impact on science products and way forward in regards to the Aqua CFPA temperature issue. The presentation can be found in the following location: http://mcst.gsfc.nasa.gov/mcst-meetings
Note to Users:
A Collection 5 QA update beginning on 02/27/13 changed the status of Terra Band 5 Detector 4 in L1B data to 'Inoperable' from 'Noisy' at the request of the science team to correct a known striping issue for higher level products that uses this Band. The QA status for this detector is 'Inoperable' for the entire mission dataset in Collection 6.
MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra (EOS AM) and Aqua (EOS PM) satellites. Terra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon. Terra MODIS and Aqua MODIS are viewing the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths (see MODIS Technical Specifications).
These data will improve our understanding of global dynamics and processes occurring on the land, in the oceans, and in the lower atmosphere. MODIS is playing a vital role in the development of validated, global, interactive Earth system models able to predict global change accurately enough to assist policy makers in making sound decisions concerning the protection of our environment.
MODIS was launched on the EOS Aqua spacecraft on Saturday, May 4, 2002 at 09:55 GMT. MODIS Aqua "First Light" was achieved when the MODIS Nadir Aperture Door opened on June 24, 2002 at 23:22:48 GMT. The Aqua MODIS instrument began taking data using side-B electronics. For a complete look at the EOS-PM/ Aqua mission, see http://aqua.nasa.gov/.
MODIS was launched on the EOS Terra spacecraft on Saturday, December 18, 1999 at 18:57 GMT. MODIS Terra "First Light" was achieved when the MODIS Nadir Aperture Door opened on February 24, 2000. The Terra MODIS instrument began taking data using side-A electronics. For a complete look at the EOS-AM/ Terra mission, see http://terra.nasa.gov/.
